2. Emergency Plans
:_2
The
contingency planning for
the
Daya Bay plant may be divided into two
parts :
(1) On-site planning, which is the responsibility of GNPJVC.
(2) Off-site planning, which is the responsibility of local authorities
(either in PRC or Hong Kong).
GNPJVC will work out a detailed contingency plan in accordance with International practice and national control rules and regulations. At present, the relevant departments of the Chinese Government are developing "Nuclear Installation Contingency Control Rules and Regulations", "Nuclear Installation On-site Contingency Plan and Preparation Specification" and "Nuclear
Off-site Contingency Plan and Preparation Specification" etc. GNPJVC will implement all the national control rules, regulations and specifications.
Installation
In line with the above, the implementation procedures of the on-site contingency plan will be established by GNPJVC prior to the first loading of nuclear fuel. As regards the off-site contingency plan, it will be established by the, relevant department of the government and the local authorities.
The on-site contingency plan involved the following main facilities :
(1) Control Room
Direct control of the plant is maintained by station operations staff following defined operating procedures. Their centre of operations is the control room which contains extensive instrumentation of plant parameters and all necessary control facilities.
The control room staff retain direct control of the plant under all conditions, whether normal operation or in the event of any incident. The only exception is the remote possibility of any incident which affects the control room itself. In that case there is a separate facility with sufficient instrumentation and control to enable the plant to be shut down safely.
(2) Technical Support Centre
This facility is separate to the control room and would only be used in the event of an incident. It does not provide a means of controlling the plant (this remains the function of the control room) but does contain instrumentation and mimic diagrams which are connected to the control room. The purpose is to provide a display and printout of key parameters which enable a continuous evaluation to be made of the status of the plant and the
progress of any incident.
